Wind direction weighted filtering-based automatic yaw controlling method for wind generating set

The invention belongs to the technical field of wind generating system controlling and particularly relates to a wind direction weighted filtering-based automatic yaw controlling method for a wind generating set. The wind direction weighted filtering-based automatic yaw controlling method includes setting a select time t of a yaw control system of the wind generating set, and acquiring a yaw angle error array Wd of the yaw control system of the wind generating set in the select time; setting weighting coefficients of yaw angle error values of the yaw control system of the wind generating set during the select time; acquiring the yaw angle error values after weighting filtering, and performing yaw control on the wind generating set according to the yaw angle error values after the weighting filtering.
